Research on comparative Germanic syntax has for a long time been stimulated by the challenge of Icelandic, a language singled out by a great number of 'peculiar' phenomena not attested (to such a degree) elsewhere (Maling & Zaenen 1990; Thráinsson 1994; 2007). The aim of our workshop is to bring together researchers more narrowly concerned with the proper analysis of Icelandic with researchers interested in comparative Germanic syntax who would like to test and broaden their views in light of the 'Icelandic challenge.' We particularly welcome attempts at bringing in evidence from the interfaces of syntax with morphophonology and prosody as well as semantics/pragmatics. Given the long and virtually uninterrupted literary documentation of Icelandic, this language is an ideal testing ground for theories of language change. Therefore, we also encourage contributions from historical linguistics.
